Where does Ardour search for plugins on OS X, and how can I change it? Especially what is the LADSPA and LV2 search path?
LADSPA_PATH is still respected as well as LV2_PATH going off memory. Set those environment variables and it should search there. Other than that it searches in /Library/Audio/Plug-Ins/LADSPA for LADSPA and I would bet similar for LV2. Along with folders in it's own bundle IIRC.
